- Thyroid nodules (adenomas)
- Inflammation of the thyroid (thyroiditis).
- Previous radiotherapy to head and neck.
- Family history of thyroid cancer especially medullary cancer.
- Low iodine levels.
Below are the six types of thyroid cancer:
- Papillary: This is the most common type of thyroid cancer.This is more common in people with obesity.
- Follicular: This is a less common type of thyroid cancer, usually found in older people.
- Medullary: This grows from the C cells in the thyroid gland and is a rare type of thyroid cancer that runs in families.

How is thyroid cancer diagnosed?
Single thyroid nodules are most likely to be malignant, especially in people who are less than 30 years and older than 60 years of age. Ultrasound scan of the thyroid is the first investigation followed by biopsy if the scan shows suspicious areas in the thyroid gland. Biopsy is done using a fine needle also called FNAC (Fine needle Aspiration Cytology).
What are the treatment options for thyroid cancer?
Most types of thyroid cancer can usually be treated successfully by an oncologist. Treatment depends on the type of cancer. Treatment options include one or a combination of:
- Radioactive iodine
You will need regular check-ups, blood tests like thyroid function test, thyroglobulin and occasionally, scans. You should have a regular follow up by an oncologist and a thyroid specialist.
